GEORGE .DURHAM, MAR SLHBAT'E l/lfa flut N7 FISHING FLOAT BACKGROUND OF THE INVENTION Historically, with the passage of time, fish change in their habits very little, yet the method and apparatus by which fish may be caught has drastically changed within the last decade. ,Until just a few years ago fishing floats were made exclusively of cork or wood and the.

easily fitted into the modern tackle box, durable and low in cost, and should be provided with means by which it will become illuminated when activated by a fish. It is further desirable that' the float be compatible with modern fishing lines, lures, and rods; and can be hermetically sealed in a manner to permit subsequent repair or replacement of parts. It is also desirable that such an improvement in illuminated floats have associated therewith a minimum of parts so as to simplify its construction as well as providing low cost, trouble free operation.

SUMMARY OF THE INVENTION.

This invention comprehends the fabrication of an illuminated fishing float forattachment to a fishing line and lure comprising a hollow plastic body which will float in water and whichfurther includes a seal member removably attached to the body, with another member in the form of a dome being diametrically opposed to the seal member. Attached to the seal member and disposed within the body of the float is a battery, a spiral spring, and a miniature bulb. The bulb is threadedly engaged 'to a marginal end portion of the coiled spring and the batteryis threadedly secured to the opposite marginal coiled portion of the spring so that the bulb, battery, and spring are'coaxially aligned with one another within the float body. The center contact of the bulb is slightly spaced apart from the center contact of thebattery thereby forming a normally open switch means.

The seal member includes a rubber wafer which serves as a diaphragrnthrough which there sealingly extends an actuator shaft having a free terminal end portion removably affixed to a fastener means. The shaft is a continuation of the upper marginal end of the wire which forms the coil spring. Accordingly, when the shaft is placed in tension, the bulb is biased toward the battery to thereby complete the circuitry from the battery, through the spring, through the filament of the bulb, and back to the central terminal of the battery, thereby causing the bulb to become illuminated.

The rubber wafer of the seal member is provided with a needle like puncture through which the shaft forcibly depends so as to provide a diaphragm which hermetically seals the interior of the float and which flexes so a as to enable movement of the shaft relative to the hollow body of the float.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT FIG. I shows a fishing float made in accordance with 7 ring 15, which may be identical to ring 11, with the ring being fitted into the illustrated eyelet which telescopically receives the free depending end of shaft 16. The shaft freely depends from a seal member 17. Line 18, which can be a continuation of line 10 and 14, is attached to a weighted lure 19. The lure can take on any number of different forms.

Lever or shaft 20 is a continuation of shaft 16 and is bent horizontally at 20 and at an angle at 20". At 21 the lever is bent to form a coil or spring. The coil is of a diameter and pitch which permits the threaded base of a light bulb 22 to be threadedly received therewith. The light bulb naturally has a filament therewithin. The coil continues as seen at 21' in FIG. Zand forcibly receives the upper marginal end portion of battery 23 in close fitting tolerance therewithin. Hence, the coil makes electrical contact with the case or exterior surface of the battery. The base or lower marginal end portion of the battery is force-fitted into the illustrated cavity of seal member 17 so as to firmly anchor and support the battery within the cavity in a manner indi-.

cated by the arrow at numeral 24.

The arrow at numeral 26 illustrates that the central bulb terminal (or central electrical contact) is normally open, or spaced apart from the central terminal'(or electrical contact) of the battery.

The seal member is apertured at 27 so as to provid a bearing surface in the form of a passageway for reciprocatingly receiving an intermediate straight marginal vertical portion of the shaft. The rubber wafer 28 is provided with a centralaperture in the form of a puncture which facilitates insertion of the enlarged end portherethrough. A second partially flattened or deformed end 32 permits flattened portion 29 of the shaft to be telescopically inserted therethrough. Central portion 33 is of a constant diameter. Portion 32 can be telescopingly received in a reciprocating manner within aperture 27, if desired.

As seen in FIG. 5, a do-nut shaped piece of plastic 34 can be forced against the outer periphery of the wafer to sealingly press the wafer against the bottom of cavity 35. Alternatively, do-nut 34 can be an integral part of seal member 1'7 and spaced closely adjacent the wafer in order to form annulus 34. Annulus 34 receives the outer peripheral marginal edge portion of the wafer in sealing relationship therewithin.

One method by which spring 21 can be fabricated is to wind the spiral portion, leaving an elongated straight depending end portion. The depending end is bent from a horizontal to a vertical position 20, then given an inclined bend followed by a second horizontal bend 20' and a second vertical bend to provide shaft 16. The completed spring is best viewed in its entirety by referring to either of H68. 2 or i.

The battery and bulb are next mated to the marginal free ends of the spring by merely screwing or forcing the spring over an uninsulated terminal end portion of the battery. The bulb 22 is screwed into a position which leaves the central electrical terminal of the battery and the bulb spaced apart from one another a minute amount as seen in the exaggerated illustration at the arrow identified by numeral 2%.

wafer 28 is punctured with a needle and carefully guided over enlargement 29 and into the relative position of FIG. 4. Washer 128 (FIG. 4) is placed on shoul der 25, and then the battery is forced into the cavity of the seal member, care being taken to align each vertical portion of the shaft with apertures 27 and 27'.

End member 30 is next attached to the enlarged portion Ziiby merely aligning the members in the manner of FlG. 8. Member 3i) is then rotated 90 to achieve the configuration seen in FlGS. 4i and 7. The completely assembled apparatus of EKG. t is next screwed into the lower extremity of the housing and the light bulb is reor other suitable fishing line holding device, through spiral ring 11, around the housing and through spiral ring 115, and lastly attached to a fish hook. Any' type v lure can be used at 19 and the line lid can be of any desired length. The entire apparatus floats with most of the illustrated structure above water level because of its back through the spring to the outer metallic housing of the battery. As soon as the downward force is removed the spring again opens the contacts. Therefore,

a fish nibbling at the lure will cause a series of erratic flashes from the electric bulb.

Since the movement required to complete the circuitry is extremely small, deformation of the wafer is of a magnitude which requires no relative motion between the shaft and the pinhole formed in the wafer. Instead, the wafer acts as a diaphragm with movement or flexing occurring along the intermediate circumferential area thereof.

It should be noted that the wafer and the base of the battery provide spaced apart opposed stop means between which the horizontal bend at 20' can abut should an undue force be placed on the fastener 30. The sloped portion 20 will bend like a spring which prevents injury to the apparatus should the horizontal portion be forced into engagement with the wafer. Moreover, when sufficient tension is applied at 18 the slack will disappear at 14 since the line is slidably received through the spiral rings at ll and 15.

It is preferable to fabricate the upper and lower hemispheres forming the hollow body of different colored plastics with the dome 12 being made of clear plastic so as to provide an attractive illuminated fishing float which is visible from a considerable distance. For example, the upper half of the dome can be red, the lower half blue, and the dome 12 of clear transparent material which will enable the fishing float to be used as a flashlight at night by merely pulling on the shaft. The apparatus can be left in the tackle box in its standby configuration until needed for fishing. Modern leakproof batteries exhibit an unusual long shelf life and enable storage of the float in a tackle box for long periods of time. Since the bulb is loosely supported within the dome cavity, the battery secured within the seal means, and a spring disposed therebetween, the resultant mechanism is rugged and will survive a considerable amount of abuse.

Disassembly of the fishing float is accomplished by reversing the above outlined assembly procedure.
